Answer:
first one is A) 21
second one is D) 150
Step-by-step explanation:
first one : add all marbles = 10
there are 3 red
chances of picking a red 3/10 or 30 percent or .3
multiple 70 by .3 and get 21
second one:
A = 6
(Surface area of cube)
600 = 6
a = 10
half of 10 is 5
6(
) = 150
Answer: See below
Step-by-step explanation:
a) 6(3x+4y-8)
Use the distributive property:
6*3x + 6*4y - 6*8
18x + 24y - 48
<u>So D is the correct answer</u>
b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.
12+4x
= 4(3+x)
<u>So D is the correct answer</u>
c) When you expand both <u>C and D</u> and simplify, you get 16x+36 as solution
d) 14x+2y+10z
Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times
14x+2y+10z
= 2(7x+y+5z)
<u>So D is the correct answer again ;)</u>
Answer:
f(6) ≈ 31
Step-by-step explanation:
If f(x) varies directly with x, we can write f(x) this way:
f(x) = kx
Using the given values, we can find k:
f(25) = k×25 = 130
k = 130/25 = 5.2
Then for x = 6, we have ...
f(x) = 5.2x
f(6) = 5.2×6 = 31.2
Rounded to the nearest whole number, ...
f(6) ≈ 31
